Progress and Research on Self-Toughening Si_3N_4 Ceramics

Zhao Zhienb

Abstract

Recent anvanceincnts of research on Self-Toughening Si3N4 ceramics were reviewed. The growth nleclla1nsin and all kinds of effect factors on Self-Toughening Si3N4 ceramics, as well as mechanical and physical properties, snch as the fracture toughness, strength, Weiball modulus, R-curve behavior, fatigue behavior, creepbehavior, oxidation behavior, thermal shock resistance, thermal conductivity were discusscd and analyzed. Thekey technologies of toughening for Self-Toughening Si3N4 ceramics are the control of the size of elongated Si3N4 grains and the proper choice of glass phase.
